Lenovo has 2 models of the Moto G4 Plus available -- one with 2GB of RAM and 16GB of storage, and one with 3GB of RAM and 32GB of storage.

Strangely enough, someone who ordered the 3GB/32GB model received a phone that only had 2GB of RAM. The 32GB of storage was correct, so it may be a manufacturing error. It's not yet know how widespread this issue is.
